In this paper, we demonstrated a digital predistortion (DPD) algorithm to linearize an electro-absorption modulated laser (EML) used to modulate a 40-Gbps orthogonal frequency division multiplexing (OFDM) signal onto an optical carrier. We characterized the EML as a nonlinear model based on memoryless polynomials. The nonlinear coefficients were estimated(More)
A technique is proposed to measure the high-resolution and wide-band characterization of amplitude, phase responses, and polarization property of optical components. This technique combines the optical spectrum stitching and optical channel estimation methods. Two kinds of fiber Bragg grating based Fabry-Perot cavities with ultrafine structures have been(More)
